OVERVIEW of Kalrez® Industrial Grades |
Kalrez® Industrial Grade O-Rings & Seals
Kalrez® Compound 4079
A low compression set compound for general-purpose use in O-rings, diaphragms, seals, and other parts used in the process and aircraft industries. It is a carbon black-filled compound with excellent chemical resistance, good mechanical properties, and outstanding hot air aging properties. It exhibits low swell in organic an inorganic acids and aldehydes and has good response to temperature cycling effects. A maximum operating temperature of 316ºC (600ºF) is recommended, with short excursions to higher temperatures possible. This compound is not recommended for use in hot water/steam applications or in contact with certain hot aliphatic amines, ethylene
Kalrez® Compound 6375
A carbon black-filled compound for general use in O-rings, seals, diaphragms and other specialty parts specifically for the chemical process industry. This compound has excellent, broad chemical resistance, good mechanical properties, and outstanding hot-air aging properties. 6375 is well suited for mixed process streams because of its excellent resistance to acids, bases, and amines. In addition, it is the suggested compound for use in hot water steam, ethylene oxide and propylene oxide. A maximum service temperature of 275ºC (525ºF) is recommended.
Kalrez® Compound 1050LF
A general-purpose compound for O-rings, seals, and other parts used in chemical process industries. It has good hot water/steam, excellent amine resistance, and enhanced compression set properties. Maximum recommended service temperature of 288ºC (550ºF). Not recommended for use in organic or inorganic acids at high temperatures.
Kalrez® Compound 1058
A carbon black-filled compound that has been plasticized with a perfluorinated oil. It is the softest, lowest modulus compound available. Generally, it is similar in chemical resistance to Compound 1050LF; it has an upper service temperature of 260ºC (500ºF). Typically used in applications that require how sealing force or high extensibility including liquid chromatography septa, seals/seats for relief valves and tubing. Its shrinkage is greater than other Kalrez compounds; therefore, finished parts may differ from standard specifications.
Kalrez® Compound 3018
A carbon black-filled compound similar to Compound 1050LF, except for higher hardness/modulus. This compound offers the best hot water/steam resistance and the best high pressure extrusion resistance. Generally used in oil field and process industry applications where these properties coupled with good amine and general chemical resistance are required. A maximum service temperature of 220ºC (428ºF) is recommended.
Kalrez® Compound 2035
A carbon black-filled compound that is well suited for selected applications in the finishing equipment, pharmaceutical, semiconductor, and chemical transportation markets. Compound 2035 has excellent chemical resistance exhibiting low swell in organic acids, inorganic acids, esters, ketones, and aldehydes. This compound is suggested for use in the ethylene oxide and propylene oxide applications. It also offers good mechanical properties. A maximum service temperature of 220ºC (428ºF) is recommended.
Kalrez® Compound 2037
A non-black-filled compound that is well suited for selected applications n the pharmaceutical, semiconductor, and other markets that demand high purity elastomers. Compound 2037 has excellent chemical resistance exhibiting low swell in organic acids, inorganic acids, esters, ketones, and aldehydes. it also offers good mechanical properties. A maximum service temperature of 218ºC (425ºF) is recommended.
